Well I own both and I like both for different reasons. The demo for Vue 4 will be out in sept. right now you can download a demo of Vue 3. I am still playing with both right now, and to tell the truth I am trying to do the same image in both to compare programs for my own knowledge. I like the vegetation in Vue much better. The tree lab is fun but as far as I have found the trees aren't as realistic looking.The new atmosphere editor in Vue makes some beautiful skies(I also find it easier to place the sun in Vue)I know I have mentioned Vue more but I really like both programs,but Vues improvements were more dramatic,IMHO. You can ask me any questions you want and I will see if I can give an answer. Marge
